- W4366259968 abstract "Catalytic cracking–dehydrogenation of hydrocarbon fuels with hydrocarbon-soluble metal nanoparticles is an appealing way to improve fuel heat sink in a high-speed aircraft. In this work, two hydrocarbon-soluble metal nanoparticles (Pd@ILs and Pt@ILs) by using symmetrical imidazolium ionic liquids (1,3-bis(14-alkyl) imidazolium bromide) as protective agents were successfully synthesized. The catalytic performance for cracking and dehydrogenation of decalin-based nanofluids was investigated using an electrically heated tubular reactor. In comparison with Pd@14N with the conventional tetradecylamine ligand, Pd@ILs and Pt@ILs catalysts exhibited smaller average particle sizes and showed better performance in terms of dispersion stability, thermal stability, and catalytic activity. Fourier transform infrared (FT-IR) and density functional theory (DFT) calculations demonstrated that the strong affinity of C atoms in the conjugate imidazole ring to the metal surface allows these nanoparticles to be stably dispersed in decalin for at least 2 months. In the quasi-homogeneous conversion of decalin, Pd@ILs exhibited the best performance in promoting fuel cracking and dehydrogenation conversion with the highest yields of hydrogen and unsaturated hydrocarbon products, especially aromatic products, thus enhancing the heat sink of nanofluids. Particularly, the heat sink of nanofluids with the Pd@ILs catalyst was 3.39 MJ kg–1 at 700 °C, which was 0.58 MJ kg–1 higher than that from decalin thermal cracking and 0.43 MJ kg–1 higher than that of the nanofluids with the Pd@14N catalyst. In addition, Pd@ILs nanofluids gave the highest heat sink of 3.61 MJ kg–1 at 725 °C. The significant enhancements are attributed to cooperative interplay between the initiation effect of ILs and the remarkable catalytic ability of Pd nanoparticles in cracking–dehydrogenation reaction, as well as the unique properties of Pd@ILs, including smaller Pd particle size, more accessible surface Pd active sites, and higher thermal stability. This work shows that symmetrical imidazolium ionic liquid-capped metal nanoparticles can serve as effective quasi-homogeneous catalysts for enhancing heat sink of hydrocarbon fuels through catalytic cracking and dehydrogenation." @default.
